[PWGJE] Rename Ds jet task and add THnSparse histograms

[monamelop]

Hi,

This PR renames the Ds jet analysis task and introduces THnSparse-based observables.

Changes:

• Rename task: jetDsSpectrumAndSubstructure -> jetDsSpecSubs
• Update workflow name accordingly
• Add THnSparse histograms
• Add corresponding workflow entry in CMakeLists

The task jetDsSpectrumAndSubstructure was introduced during development and is not used elsewhere. This PR consolidates the final version under the name jetDsSpecSubs.

This PR has been cleaned and rebased on the latest master to include only the relevant changes.

Please let me know if you would prefer splitting the rename and the new features into separate PRs.

Thanks!

No, it doesn't look reasonable.

I rebased the branch on the latest master and cleaned up the changes.

• The task was renamed from jetDsSpectrumAndSubstructure to jetDsSpecSubs.
• I also removed the unused AOD table and simplified it to a histogram-only task.
• The CMakeLists.txt was updated accordingly to reflect the new task name (jet-ds-spec-subs).

The code runs correctly locally now.

Hi,

The CI failure is due to O2 linter errors in PWGJE/Tasks/CMakeLists.txt related to workflow naming inconsistencies (e.g. emcCellMonitor, photonIsolationQA, etc.).

These are pre-existing issues and not introduced by this PR. My changes only affect the renaming of my task (jetDsSpecSubs), and I did not modify the other workflows.

Please let me know how to proceed.

Best,
